Title: Device for detention part of telescopic type jib and method thereof
Inventor: ERDMANN GERD
IPC: B66C23/70
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To make the part of a telescopic type jib so as to be detainable at any position by making it movable to a second part and utilizing the connected sliding element, then detaining any motion in the second part, and further redetaining the motion of the second part against a first part with a manual element. SOLUTION: When load is added to a telescopic type jib, this load adds force to an inner part 2 so as to increase an extent of contact force in space between a sliding element 3 and an inner surface of an outer part 1, and in a gap with a guide surface 9, respectively. When this telescopic type jib's load grows larger, contact pressure is increased, preventing any undesirable retraction in the inner part, and the inner part 2 is stably and securely locked to the outer part 1. Consequently, in order to detain the inner part 2, such a spring storage device that adds force to a direction of separating from the guide surface 9 to shift the sliding part 3 to a detention position falls into disuse. Instead of that, at a time when the load is added to this telescopic type jib, the inner part is automatically detained.

Title: Synchronous rectification circuit
Inventor: TAKASHIMA TOYOTAKA
IPC: H02M3/28
Filed: 1998-12-11
Abstract: PROBLEM TO BE SOLVED: To retain a stable gate voltage by superposing a secondary coil winding voltage and a tertiary coil winding voltage and applying them to a MOSFET for commutation as a gate signal voltage by switching or applying only the secondary coil winding voltage or the tertiary coil winding voltage in negative biasing. SOLUTION: Since the positive voltage of a pulse transformer T2 is outputted with a coil winding ratio of N1:(N2+N3) even if duty becomes small during PWM control, a gate voltage is given satisfactorily. Since a negative voltage does not exceed the rating of the gate voltage due to the number of turns of N1:N2, it is increased by the positive voltage. As a result, by switching the secondary side coil winding voltage of the pulse transformer for utilizing as a single or superposition gate signal, a stable gate voltage can be retained by adjusting the number of turns and the ratio of the number of turns of each coil winding even if the duty ratio of an input pulse width signal changes, thus reducing loss.
